All evidence suggests BMW is working heavily on weight management and lightweight materials. Absolutely no doubt about that. So, clearly the car will weigh less than it otherwise would have if not for these initiatives. But how much the final product weighs relative to other BMW products - past or present - is unknown. Certainly they are not going to decontent the car to meet some arbitrary weight cutoff point, they are not going to produce a near-exotic $100k+ M3 just to avoid crossing some line in the sand, and most importantly, they certainly are not going to compromise on engineering, longevity, safety, and reliability.

I don't understand why this is so hard to see. F3x m3 weighing less than E46 m3?
